DSP 7265 Lock-in Amplifier

class pymeasure.instruments.signalrecovery.DSP7265(resourceName, **kwargs)

Bases: pymeasure.instruments.instrument.Instrument

This is the class for the DSP 7265 lockin amplifier

adc1

Reads the input value of ADC1 in Volts

adc2

Reads the input value of ADC2 in Volts

dac1

A floating point property that represents the output value on DAC1 in Volts. This property can be set.

dac2

A floating point property that represents the output value on DAC2 in Volts. This property can be set.

dac3

A floating point property that represents the output value on DAC3 in Volts. This property can be set.

dac4

A floating point property that represents the output value on DAC4 in Volts. This property can be set.

frequency

A floating point property that represents the lock-in frequency in Hz. This property can be set.

harmonic

An integer property that represents the reference harmonic mode control, taking values from 1 to 65535. This property can be set.

id

Reads the instrument identification

mag

Reads the magnitude in Volts

phase

A floating point property that represents the reference harmonic phase in degrees. This property can be set.

reference

Controls the oscillator reference. Can be “internal”, “external rear” or “external front”

sensitivity

A floating point property that controls the sensitivity range in Volts, which can take discrete values from 2 nV to 1 V. This property can be set.

setDifferentialMode(lineFiltering=True)

Sets lockin to differential mode, measuring A-B

shutdown()

Brings the instrument to a safe and stable state

slope

A integer property that controls the filter slope in dB/octave, which can take the values 6, 12, 18, or 24 dB/octave. This property can be set.

time_constant

A floating point property that controls the time constant in seconds, which takes values from 10 microseconds to 50,000 seconds. This property can be set.

values(command)

Rewrite the method because of extra character in return string.

voltage

A floating point property that represents the voltage in Volts. This property can be set.

x

Reads the X value in Volts

xy

Reads both the X and Y values in Volts

y

Reads the Y value in Volts
